(57) Impact absorbing device (1) of the type made up of pneumatic chambers (1,2) designed
to protect fragile elements (7) such as calculators, electronic plates (circuits),
measuring instruments, remote controls and a the similar ones. It consist of a first
impact absorbing chamber (2) at the bottom and a top flexible cover (3) which rests
on the mentioned first chamber (2). The chambers (1,2) can be inflated through an
entrance valve (4) for exterior air, carbon dioxide gas, or gases generated through
a chemical reaction produced by reacting elements contained inside the first chamber
(2). The top flexible cover (3) can have a Velcro® type clasp or similar. It gets
a perfect filling and therefore the pressure of the mentioned chambers (1,2) on the
protected element (7) due to the fact that the hole or perforation for the gas to
go into the second chamber is placed on the opposite side to the ingoing perforation
of the first chamber (2) or, correspondingly, from the place where the gases are generated;
which will fill the impact absorbing chambers (1,2).
